Diffusion point-type gas detectors measure the amount of gas over a small area. The SafEye 800 Open Path Gas Detection System measures the gas cloud concentration over many meters where the gas concentration will not be uniform. Instead of the gas measurement unit of % LEL for the flammable gas, widely used for point-type gas detectors, the unit of measurement for open path is the LEL meter.
The SafEye Xenon 800 detector uses a dual-beam concept. One detector wavelength is chosen as the reference that measures and adjusts for environmental effects, but is unaffected by gas within the beam path. The second sample wavelength is chosen to measure the target gas. The ratio of the two beams is continuously compared. When no gas is present, the two signals are equal. When a hydrocarbon gas cloud crosses the beam, the sample signal is absorbed or reduced in proportion to the amount of gas present, while the reference is not. If obscuration of the beam occurs as a result of fog, rain or other adverse weather conditions, both beams are affected equally.

Gas Detection
- The SafEye Xenon 800 System is an open path gas detection system using advanced Xenon Flash Source technology to provide fast, reliable detection of a wide range of hydrocarbons.
- This detection system detects combustible gases below the lower explosive limit (LEL) over an open path up to 120 meters.
- The reliable technology used in the SafEye Xenon 800 Gas Detection System has excellent operational records in installations ranging from the African deserts to hot and humid regions of Asia, the wet and cold North Sea, and the dry cold regions of Alaska.
